p Application filed. January 7, v199,0. SeralNo. 349,884. p

To all whom t may concern:

Be itknown lthat'l, OTTO H. Morin, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful'Improvementsy in Reflector Shades; and I ldo hereby declare thefollowing to be a full, clear, and exact .description ot the invention, such as will enable others skilled in ,they artto which it appertains to make and.

use the same.

.Myipresent invention relates'to .the sub-l ject "of illumination by agency of ,artificial light, but more particularly to an even dis tribution of light from a givensource for illuminating purposes; as also to structural means for accomplishing such uniformity of distribution throughout the entire lighted area. p

Thisinvention has for an object .the production of a combined light shade and reflee-tor arranged land adapted to deliver either directly .or indirectly, a flood otsoft, rellected, diffused light in a multiplicity ofv independent rays or beams, to a given working illuminated area, and at the same time to permit the escape directly through said shade and reflector, oi' a predetermined amount of light, Alikewiseyin independent rays or beams of uniformy intensity, regardless of the position of the light source. A further object of this invention is ythe production of acombined shade and reflector, hereinafter termed a reflector-shade,v

A further object is the production ,of an' opaque reflector-shade having the vcharacter,- is'tics aforesaid, made of interwoven or intertwined metallic strips highly polished upon their reiiecting sides.

A further object is the production of a simple, durable, non-breakable, light-weight,

and comparatively` economical relectoi shade for general use and application 1n place of thetragilevglass units ordinarily employed for commercial, industrial and interior lighting, either fixed or portable.

A. further object is the production of a non-breathable, semi-indirect, ventilated Kre? Hector-shade of Kthe character indicated, which is at alltimes self cooling, and atv all times capable ofy breakingv upy or diffusing both reliected and direct light rays yfrom more or less `brilliant sources, thereby insuring` an even, ,uniform and agreeable distribution of light fand the elimination `of harsh shadows. i f 'i .With lthe foregoing and other objects v1ew,the.1nvention will be hereinafter "morel particularly pointed out and then set forth by the appended claims. i

The accompanying drawings, which ,form part of this application for Letters Patent, andwhereon like numerals, indicate corresponding parts in both views; exemf. plity an vembodiment. of my presentk invention comprising a reflector shade` in'. this in* stance of concave: form, wherein:v Figure l is a perspective view showing af bowl or reflector shade by dotted lines, and asmall portion-only of the all-overwoven form of construction; and f Figure 2 isa relatively enlarged "frag,- mentary sectional view, showing in vertical section the woven ,characteristics of the re'- liector-shade, a' spot. indicating a source of. light, and a few only of the light rays bothv reflected and direct. p

Reference being had to theser` drawings and numerals thereon,` l indicates a wire, frame, inthe present instance of annular or ring lorm, serving, as .a `finishing bead or binding for the completed structure. Se# cured to the ring" lat 4points diametrically opposite, are the oppositeends of main body ally tapered in width toward thea'center from opposite ends, for thev purposer of .collectively converging toward thev center ofthe shade structure, and for the purpose also of insuring proper spacing between them.' f

Interwoven with said' main strands 2 is a series ot`-circular horizontally positioned body strands 3 in parallel arrangement, thus constituting` a woven pattern of pleasing` design. The vertical and horizontal strands 2 and 3, respectively` may of course, be made of any approved materials, but an lli) opaque material is desirable, and to this end flat ribbon-like strips of metal, preferably copper, are employed. Upon one side at least, namely the reflector side, of the completed structure, strands 2- and 3 are highly polished and finally silver plated to constitute reflecting surfaces. And, because of the over and under interwoven relation of all strands 2 and 3, it will be obvious. that a multiplicity of small independent substantially convex reflecting surfaces or mirrors are produced, which, while giving back light from a common source, thoroughly soften and diffuse that light, dividing it into an almost innumerable number of reflected rays, a few of which, the direct ones only, being indicated diagrammatically by Figure 2 of the drawings, wherein a indicates a source of light, and a, b, c, the reflected rays aforesaid.

Obviously all reflected rays, thus softened and diffused, are returned into the illuminated area, of a room for example, by reflection from a ceiling above, or from a superimposed reflecting unit, not shown, inv

the usual and Well understood manner. It will be particularly noted however, that direct rays, a few of which are indicated on Figure 2 by the lines a, CZ, are filtered directly through interstices formed between the interwovenstrands 2 and 3, into the room or .other illuminated area, with a peculiarly uniform and even distribution, due to the prearranged spacing of the said woven strands 2 and 3, with relation to the position of the light source a. If such position is asindicated by Figure 2 it will be apparent that the spacing of these strands from the lowermostto the uppermost portions ofsaid figure must be gradually increased in order to insure the escape of an equal amount of light from each.

In this `manner the comparatively small volume of light escaping directly from a reflector-shade may be regulated and determined by the relative closeness 'or looseness of the'weaving, so asto meet varying requirements'. A very small quantity being necessary to relieve thev outer surface of a reflector-shade from shadow, or to sufficiently illuminate the surrounding` silk shade of a portable or floor lamp; and a relatively increased quantity being required to light the side walls of a room.

Having thus described my present invention, it should be understood that I do not consider myself restricted to the form and arrangement of parts shown and described, since these maybe varied indefinitely without in the least departing from the spirit of this invention involving broadly the idea of a combined reflector and shade unit, made of woven material with light-emitting openings of. a size and location proportionate to the position of the light source. And I consider it entirely within the scope of this invention to include reflector-shades having the characteristics aforesaid, regardless of what materials or of how formed, as for example of pressed steel in imitation of basket work, or of expanded metal.

What I claim therefore and desire to secure by Letters Patent is:

l. An interwoven reflector-shade broken by light emitting openings' varying in size proportionally to the distance of each from the relatively fixed location of a light source.

2. An interwoven reflector-shade broken by light emitting openings varying in sizev proportionally to the distance of each from the relatively fixed location of a light source, and provided with a multiplicity of reflecting surfaces. 4

3. A reflector-shade broken by light emit'- ting openings varying in size proportionally to the distance of each from the relatively fixed location of a light source, and formed of interwoven opaque strips having reflecting surfaces upon one side.

4. A reflector-shade of the character described having a multiplicity of convex re' fleeting mirrors upon its interior, and formed of interwoven strips flanked by a multiplicity of light emitting openings, varying in size proportionallytotheir distance from the light source.

5. A reflector-shade of the character described having a multiplicity 4of independent reflecting mirrors upon itslight side, and perforated by a multiplicityk of light emitting openings proportionate in size to the relatively fixed location of a light source whereby each of vsaid openings permits passage of an equal amount of light'.

6. A reflector-shade of the character described having a multiplicity of convex reflecting mirrors upon its light side, and perforated by a multiplicity of .variable light emitting openings proportionate in size to the relatively fixed location'of a liglit source whereby uniform distribution ofy both the reflected and direct light is obtained.

In testimony whereof I affix my signature, in presence of two subscribing witnesses.
